3 Mechanical limit signal PEL & MEL (axis control signal / DI signal)
Endpoint setting function: in general, when executing motion control, users will set two limit
sensors between a fixed distance. Setting the moving range of the motion axis avoids the risk of
improper mechanical operation or control. The PEL and MEL endpoint sensor signals are
connected to the PCI-M324 and servo drive at the same time, so that both the drive and the
control card can effectively stop the motion beyond the allowable moving range.
